How long should it take to install a heater valve in 2000 Jag S type?

Answer 1

Ok//////here goes......first remove plastic covering across top of radiator.....next remove left radiator bracket.....3 bolts.....remove hold down strap on ac canister....1 bolt...pull canister to left ....I tie it out of the way.....coolant control valve has five hose connections.....o ring disconnects on 3 leading to heater core/coolant tank..... one tee's into bottom of radiator hose....remove this radiator hose....by removing from top of radiator connection and connection to bottom of bleed cap....this has a support bracket ....which must be removed....now you should see recirculating pump on S type....remove two hold down bolts on recirc. pump...now for the hard part.....you will remove recirc. pump and heater valve at same time.....the hose connection from recirc. pump to heater valve will stay connected.....the heater valve has a bolt on left side at very bottom and a nut attachment on the right side....nut can just be loosened...bolt must be removed.....be sure to have a 10mm....standard socket, extended socket, open end, and box end.....1/4 drive....not much working room..and difficult to see attachment nut/bolt.....need a good flashlight/troublelight....remove electrical connection from recirc. pump and coolant valve.....after removing pump/attached valve..from car....disconnect pump from valve....remove solenoid heads....6 torx screws...now manually operate valves and back flush....were pump was attached...spray silcone spray into pump connection and hold upside down for a few seconds.....lubrication to prevent sticking....good time now to back flush radiator....heater core and coolant tank...all disconnections have been previously made to accomplish this....now put in reverse....and .....check all connections carefully....be patient....refill coolant system thru bleed cap....be sure to size Allen wrench carefully....to remove and tighten....fill coolant tank....crank car let warm slightly....remove bleed cap....top off and check coolant tank level....crank again...warm to operating temp...be sure to turn heat on to max.....while reaching operating temp...cut car off...turn key back on but do not start.....run heater max....until temp... is in blue or cool zone....this will take a few minutes....this will draw coolant from coolant tank...and aid in removing any air pockets...do not rush this....if temp. needle goes past normal operating temp....turn off asap and run another heater cycle cool down..do not drive car out on road until you are absolutely sure coolant temp. is normal for a few minutes..you should be able to add a full gallon of coolant plus .....this is a fully pressurized system....including coolant tank...never use a radiator stop leak....in this type of system..if your coolant tank is leaking....replace it....that's another story.....Good Luck and Happy Motoring.....Cecil
